专利号:WO-2021035382-A1 优先权日:2019-08-23 标题:Method forcontinuous synthesis of 2-cyclopentene-1-one 发明人:HONG HAO; LU JIANGPING; BAO DENGHUI; YUAN LONG; WANG BO 权利人:LIAONING ASYMCHEM LABORATORIES CO LTD 摘要:Provided is a method for the continuous synthesis of 2-cyclopenten-1-one. The continuous synthesis method comprises: loading a catalyst in a continuous reaction device, then continuously conveying cyclopentene, an oxidant and a solvent into the continuous reaction device for an oxidation reaction, and continuously discharging 2-cyclopentene-1-one. In the presence of the catalyst and the solvent, cyclopentene is used as a starting material, and same is directly oxidized by the oxidant, which can avoid the generation of a large amount of halogen-containing three wastes; at the same time, the entire continuous synthesis process is carried out in the continuous reaction device, which can effectively inhibit the occurrence of safety risks during scale-up production; in addition, after the reaction is complete, the product system of the oxidation reaction can be simply concentrated to obtain the target product (2-cyclopenten-1-one). Thus, the purity (up to 98% and above) and separation rate (up to 79%) of the product are greatly improved, and production can be easily scaled up.
